IMPROVEMENT IN BINDING-GUIDES FOR SEWING-MACHINES.

^ Specification forming part ot' Letters Patent No; 1%,01L dated `November Q, 1851; antedated June 1, 1854. l

Be it known that I, OsGOOD G. BOYNTON, of Haverhill, in the county of Essex and State ol" Massachusetts, have invented a new and useful improvement in machinery for applying binding to leather or other material during the process of sewing (by a sewing-machine) such binding upon such leather or other material; and I do hereby declare that the samev vguide and the foot of the presser. Fig. 3 is a side view of it. Fig 4 is a sectional View taken back of the needle and exhibiting the manner in which the binding is carried through the guide.

In the said drawings, A-denotes the base or table of the machine, B, the needle slide or carrier 5 C, the needle, D, the presser; E,Vthe

. spring of the presser; G, the arm which sustains the presser and the needle-carrie1., all such being constructed essentially like those in use in various sewing-machines.A

The foot H of the presser, where it is to rest' on the material to be sewed, is formed with an angular or curved bend, as seen at e, each of the parts b c o d being made to stand at an 4 acute angle with the bed-plate or base, over which they are situated. The pa-rt c d supports and has appliedto its upper surface a bindingguide, I, which is composed of a plate of metal, f, bent in its middle, sol that the parts of it on both sides of the bend are made to stand parallel to each other and at about the thickness of the plate apart from each other. Between these parts anadjusting-plate, e, is inserted, there being an elongated slot, h, formed through both plates. Through this slot and the foot ofthe presser a confiningscrew, g, is passed, itbeing screwed into the foot and having its head resting on the top surface of the guide, and so as to notonly confine the guide and the adjusting-plate together, but

-down upon the foot. The distance of the in- Y ner edge of the adjuster-plate from the inner surface of the bend of the outer plate of the guide should be equal to the width of the binding to be used.

This guide is not intended to receive at one fend of its opening the binding in a flattened state and discharge it at the other eund of its opening in a bent or doubled state, as is the case with the binding guide of Henry L. Sweet, patented on the 20thvday of December,

A. D. 1853, but it is intended to simply lay the Strip of binding ina flattened state on the materi al to be sewed, and in such manner that the binding shall project beyond the edge of such material while it is being sewed thereto, the extent of the projection being such as will enable the binding afterward to be turned over the Said edge and stitched down to a lining, if necessary so to do. For this purpose the guide is to be arranged close to the needle and on one side of it, and the binding (seen at K) is led down from a roller, L, into and through the guide and made to rest on the article to which it is. to be sewed. Vhen a bindingguide is made to double the binding and .to embrace the. edge to which the binding is to be sewed, there are many kinds of workon parts of which it cannot be conveniently used. For

instance, it cannot be employed to advantage in applying the binding tothe Vertex of the angular slit of the vamp of a shoe, because the great acuteness of the angle prevents the guide from being worked close up into theangle. Therefore in using the guide for binding the upper edge of the Vamp it has been customary to work it up as near to the vertex of the slit as possible, and leave the remainder of the binding, or that around the vertex, to be fastened by a needle and thread in the hands of a workmanor female attendant.

With my improved guide applied directly to the foot of the presser I am enabled not only to readily work the binding around the vertex of the slit of a vamp, but the guide is made` to rise and fall with the presser as it is moved upward or downward by the varying thickness of the cloth, leather, or other material to which the binding is being applied. This is of great advantagein keeping the guide close to the cloth and the binding duly strained,
